XML::RPC(3)

NAME
XML::RPC -- Pure Perl implementation for an XML-RPC client and server.

SYNOPSIS
make a call to an XML-RPC server:

    use XML::RPC;

    my $xmlrpc = XML::RPC->new('http://betty.userland.com/RPC2');
    my $result = $xmlrpc->call( 'examples.getStateStruct', { state1 => 12, state2 => 28 } );

create an XML-RPC service:

    use XML::RPC;
    use CGI;

    my $q      = new CGI;
    my $xmlrpc = XML::RPC->new();
    my $xml    = $q->param('POSTDATA');

    print $q->header( -type => 'text/xml', -charset => 'UTF-8' );
    print $xmlrpc->receive( $xml, \&handler );

    sub handler {
        my ( $methodname, @params ) = @_;
        return { you_called => $methodname, with_params => \@params };
    }

DESCRIPTION
XML::RPC module provides simple Pure Perl methods for XML-RPC communication. It's goals are simplicity and flexibility. XML::RPC uses XML::TreePP for parsing.

This version of XML::RPC merges the changes from XML::RPC::CustomUA.

CONSTRUCTOR AND OPTIONS

  $xmlrpc = XML::RPC->new();
This constructor method returns a new XML::RPC object. Usable for XML-RPC servers.

  $xmlrpc = XML::RPC->new( 'http://betty.userland.com/RPC2', %options );
Its first argument is the full URL for your server. The second argument is for options passing to XML::TreePP, for example: output_encoding => 'ISO-8859-1' (default is UTF-8).

You can also define the UserAgent string, for example:

    my $rpcfoo = XML::RPC->new($apiurl, ('User-Agent' => 'Baz/3000 (Mozilla/1.0; FooBar phone app)'));

METHODS

  $xmlrpc->credentials( 'username', 'password );
Set Credentials for HTTP Basic Authentication. This is only secure over HTTPS.

Please, please, please do not use this over unencrypted connections!

  $xmlrpc->call( 'method_name', @arguments );
This method calls the provides XML-RPC server's method_name with @arguments. It will return the server method's response.

  $xmlrpc->receive( $xml, \&handler );
This parses an incoming XML-RPC methodCall and call the \&handler subref with parameters: $methodName and @parameters.

  $xmlrpc->xml_in();
Returns the last XML that went in the client.

  $xmlrpc->xml_out();
Returns the last XML that went out the client.

CUSTOM TYPES

  $xmlrpc->call( 'method_name', { data => sub { { 'base64' => encode_base64($data) } } } );
When passing a CODEREF to a value XML::RPC will simply use the returned hashref as a type => value pair.

ERROR HANDLING
To provide an error response you can simply die() in the \&handler function. Also you can set the $XML::RPC::faultCode variable to a (int) value just before dieing.

PROXY SUPPORT
Default XML::RPC will try to use LWP::Useragent for requests, you can set the environment variable: CGI_HTTP_PROXY to set a proxy.

LIMITATIONS
XML::RPC will not create "bool", "dateTime.iso8601" or "base64" types automatically. They will be parsed as "int" or "string". You can use the CODE ref to create these types.
